Antony Dovgal has a quick post today about a PECL extension that makes for quick and easy full-text searching on standard SQL databases.

As some of you might have noticed, I've been a bit busy lately creating new PECL extension - sphinx. The extension provides an interface to a feature-rich fulltext search engine Sphinx written by Andrew Aksyonoff. We (Andrew and me) made our best to keep the extension as compatible to the pure-PHP API (shipped with Sphinx) as possible in order to make the transition easier.

The PECL page has already been created as well as a page in the manual for how it works. He also briefly mentions the installation (including teh required libraries).
